York County now under heat warning: Index of 105 to 110 degrees expected

The heat that hit York County over the weekend will linger through Wednesday's Fourth of July holiday before cooling somewhat by the weekend, according to officials.

Tom Kines, senior meteorologist for AccuWeather in State College, had two words to describe the weather at the start of this week: "Not pleasant."

“At least for the foreseeable future, the humidity, and the heat, is going to stay with us probably right into Friday,” he said.

Heat: The National Weather Service initially placed York County under a heat advisory from Sunday through 8 p.m. Monday, but the advisory was extended until Tuesday, July 3.

However, during the day Monday, the weather service lifted the heat advisory, and instead placed the county under an excessive heat warning until 8 p.m. Tuesday. 

The weather service said the heat index will be from 105 to 110 degrees, with higher values in urban areas.

Kines said temperatures will likely dip in the lower 90s after the warning ends, but the humidity is expected to stay, making it feel hotter than it actually is.

Michael Colbert, a meteorologist intern for the National Weather Service in State College, said there is expected to be a high of 97 Monday and a high of 95 Tuesday.

With the humidity, however, it will feel like 102 Monday and 104 Tuesday, he said.

“I think tomorrow will feel pretty hot," he said Monday morning.

The weather service is expecting a high of 92 degrees for Wednesday. Colbert said it's always possible the weather service will extend the advisory again, but for now forecasters will just have to wait and see.

Temperatures are expected to drop to the 80s by the weekend, according to Kines.

“At least for a day or two, we’ll get more comfortable weather," he said. 

Both Kines and Colbert said there is a possibility that York County could see some thunderstorms during the week, as well.

Caution: For now, though, the meteorologists suggest taking it easy during the heat wave.

“If you’ve got to be outside, you've got to keep your body hydrated; drink lots of water,” Kines said.

Colbert advised against going outside during peak temperatures.
